Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed April 2,1906. Serial No. 309,385.

To all whom it may concern:

Be it known that I, J OHN E. CoUnTRIGH'r, a citizen of the United States, residing at Independence, in the county of Montgomery and State of Kansas, have invented a new and useful Improvement in Cultivators and Pulverizers, of which the following is a specification.

My invention relates to cultivators and pulverizers, and more particularly to that class adapted to the cultivation of listed corn.

The object of my invention is to provide a cultivator or pulverizer of simple construction, easy adjustment for all kinds of work, and one which is thoroughly efficient and practical in operation.

With this end in view, my invention consists in the novel constructions and combinations of parts as will be hereinafter described and pointed out in the claims.

Reference will be had to the accompanying drawings which form a part of this specification, and in which similar reference characters indicate the corresponding parts in the different figures.

Figure 1 is a top plan view of the cultivator. Fig. 2 is a sectional side elevation of the same taken on line A-A of Fig. 1. Fig. 3 is a front elevation of one of the disk gangs and adjacent parts. Fig. 4 is a perspective view of the arch connecting the bearings of the disk gangs. Fig. 5 is an enlarged side view of the clamp for connecting the arch of Fig. 4 with the pipe above the disk gang. Fig. 6 is a sectional view of the boxings and bearings at the outer end of the disk gang taken on the line 00 of Fig. 3, showing the connection of the arch of Fig. 4 with said bearings. Fig. 7 is a detail view of the front arch of the frame, showing the means for the adjustment of the width of the frame. Fig. 8 is a detail view showing parts of the bearing at the pivotal point of the gang connecting said bearing with the arch of Fig. 4.

The frame consists of a pair of runners, 12, preferably of angle steel, connected at their rear ends by an arch 18, and at their front ends by arch 15; and bars 14 extending horizontally outward at or near the forward ends of said runners. The frame is also provided with brace bars 13 attached at the upper part of the arch 1.8 and extending downward and forward to the runners 12, also attached thereto. The frame is further provided with a pair of guide wheels 11 attached inside of arch 15 to said arch by means of axles bolted thereto and the wheels secured on the axles in the usual manner.

The distance between guide wheels 11 may be regulated by the adjustment of the arch 15; said arch con sisting of two members a, b, each member having a series of openings 0 arranged to aline with openings e in the other member and the two members being secured to each other at any desired width by bolts d which are adapted to pass through openings 0 and e and be secured by nuts.

Arch 18 is pivotally connected with the rear ends of the runners 12 in order to permit the front ends of the runners to be spaced to a greater or less distance; said adjustment being secured by loosening the nuts on the staples which secure arch 18 to runners 12.

A short distance in front of the arch 18 runners 12 are bent upward (see Fig. 2) then slightly outward and horizontally forward to the arch 15. Runners 12 are, preferably, provided with stationary shields 21, at or near their lower rear, ends, rigidly attached to the runners and to arch 18.

A seat 16 may be secured to the cultivator frame in any suitable manner, preferably as shown in Fig. 1 and Fig. 2, by a seat bar 17 secured to the brace bars 13 by bolts 20, and, passing back and up over the arch 18 extend horizontally forward the proper distance to give the seat the desired position.

The transverse pipe or bar 22 above the disk gangs is secured to the arch 18 by eye bolts 19 and thereby rendered vertically adjustable upon said arch. The arches 2 are connected with the bearings 8 and 10, respectively at the inner and the outer ends of the disk gangs and secured to pipe 22 by clamps 3, one of said clamps being upon either leg of said arches. Clamp 3 is made preferably of a single casting E with a transverse opening admitting the pipe 22 and a transverse open space 26 below this opening dividing the casting in two approaching parts around pipe 22. Eye bolt D on arch 2 passes through the lower part of casting E in a hole or opening at right angles to the direction of open space 26. Bolt D is secured by a nut whichmay be tightened and thereby casting E rigidly clamped to pipe 22. Casting E is also provided with a transverse segmental slot 41 in its upper part centered to the bolt D.

7 Eye bolt B on arch 2 passes through this slot and is secured by a washer and nut. Arches 2 being provided, as aforesaid, with clamps 3 upon either side or leg, said arches may be raised or lowered in said clamps by loosening the bolts D and B, and again secured in the desired position by again tightening the nuts on bolts B, D. Arches 2 may also be tilted or adjusted to a slanting position with one side lower than the other, and thereby a similar adjustment of the disk gangs secured, by adjusting bolts B in slots 41 with the nuts on bolts D loosened to permit arches 2 to take the desired position. Clamps 3 and thereby arches 2 may be adjusted laterally upon the pipe or bar 22 by loosening the nuts on bolts D and sliding said clamps to the desired position on pipe or bar 22.

Arches 2 are constructed, as shown in Figs. 3 and 4, with their two sides or legs parallel in their upper part; but the side or leg connecting with the bearings 10 at the outer ends of the disk gangs has, at its lower end, a forwardly extending arm 24 in which there is an opening 25 to permit connection with the draft rod 6; and the side or leg connecting with the bearings 8 at the inner ends of the disk gangs curves forward and downward in its lower portion, then backward in an arc-shaped arm 4 centered to the lower end of the opposite side or leg of said arches. The outer casting of the bearings S at the inner ends of the disk gangs is provided with an opening for the arc-shaped arm 4 and by virtue of this opening the bearings 8 slide upon arm 4 when the cutting slant of the disk gang is changed by throwing lever 9 forward or backward lever 9 being mounted on the horizontal bar 14 and connected with said bearing by draft rod 7.

Bearing 10 at the outer end of the disk gang is connected with arch 2 by means of the upward extension P of the outer casting of said bearing (see Figs. 3 and 6); upward extension P, together with the casting F in front, forming a box or journal for the lower part of the leg of said arch. This box or journal has, at its lower front part, a transverse slot 23, in which slot arm 24 of arch 2 has a limited play. The opening 25 in arm 24 permits draft rod 6 to be hooked therein, which draft rod is connected at its forward end with horizontal bar 14.

Runners 12 are provided with cutting blades 5 bolted thereto; and arranged to run immediately in front of the inner disks of the gangs and serve as cutters for the inner disks, thereby rendering the soil easily turned. Blades 5 also serve, in the cultivation of listed corn, to remove the weeds from the sides of the furrow, and, be-

cause of their position immediately in front of the disks, the trash and weeds are prevented from collecting by being drawn under by the revolving disks.-

In the operation of my invention, the distance be tween the gangs, or the distance of the gangs from the row cultivated, is regulated by adjusting clamps 3, and thereby arches 2, laterally upon pipe 22. The relative depth at which the disk gangs run is regulated by adjusting arches 3 vertically in clamps 3. The relative depth to which the inner and outer disks of the gangs run is regulated by adjusting arches 2 in a tilted or slanting position in clamps 3 with one side or leg lower than the other. The depth to which it is desired to pulverize the soil is regulated by adjusting pipe 22 up or down on arch 18. When it is desired to throw the soil away from the row cultivated, or out from the center, the disk gangs are changed to opposite sides of the cultivator frame together with the levers 9, which are then placed at the outer instead of the inner ends of the bars 14. It will, also, be readily seen that by means of the adjustment of the pipe 22 upon arch l8 runners 12 may be raised entirely free from the ground and become merely a frame extending from the guide wheels 11 to the pipe 22 above the gangs.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:-
